[PATCH net] selftests: net: add missing config for NF_TARGET_TTL

[Jakub Kicinski <kuba@xxxxxxxxxx>]

amt test uses the TTL iptables module:

  ip netns exec "${RELAY}" iptables -t mangle -I PREROUTING \
  	-d 239.0.0.1 -j TTL --ttl-set 2

Fixes: c08e8baea78e ("selftests: add amt interface selftest script")
